Taug qab nyob rau hauv -rail compressive deformation thiab taug qab nruj tswj kev tswj
Q1: Dab tsi yog tus txheej txheem tswj kev ruaj ntseg compression deformation nyob rau hauv -rail pads?
A1: Cov compression deformation mus tas li ntawm tus qauv Suav nyob rau hauv -rail pads yuav tsum tsis pub ntau tshaj 15%, thiab cov ntaub qhwv tshwj xeeb rau siab - ceev thiab ballastless lem yuav tsum tsis pub tshaj 10%. Kev deformation ntau dhau yuav ua rau muaj kev nyuaj siab tam sim ntawd, lub log nce ntxiv - kev tsheb nqaj hlau cuam tshuam thiab kev puas tsuaj rau lub sijhawm ntev - kev ruaj ntseg ntawm kev taug qab geometry.
Q2: Dab tsi yog qhov kev sib raug zoo ntawm ncoo compression deformation thiab kab khiav ceev?
A2: High- cov kab ceev xav tau cov ntaub qhwv nrog cov compression qis deformation thiab kev ruaj ntseg siab kom tsis txhob ua rau lub ncoo deformation nyob rau hauv siab - tsav tsheb ceev; zoo tib yam - cov kab nrawm tuaj yeem siv cov ntaub qhwv nrog qhov nruab nrab deformation kev ua haujlwm; hnyav- cov kab tsheb thauj mus los xav tau siab - compression thiab creep- cov ntaub ntawv tiv thaiv kom tau txais cov khoom loj thiab tswj xyuas qhov kev nruj nruj.
Q3: Dab tsi yog qhov txawv ntawm compression deformation yam ntxwv ntawm polyurethane thiab roj hmab pads?
A3: Polyurethane pads muaj zog compressive siab, tsis tshua muaj compression deformation thiab zoo creep tsis kam tshaj li roj hmab pads, haum rau siab -ceev thiab hnyav- cov kab; roj hmab pads muaj elasticity zoo thiab tus nqi qis, nrog compression deformation nce sai nrog lub sijhawm ua haujlwm, tsim nyog rau kev ua haujlwm ntawm cov kev ua haujlwm zoo tib yam - ceev ballasted lem.
Q4: Cov kab mob dab tsi yuav tshwm sim los ntawm kev tsis sib xws?
A4: Kev tsis sib xws yuav ua rau tsis sib npaug ntawm lub log - kev tsheb ciav hlau quab yuam thiab hnav tsis sib xws thiab nthwv dej ntawm cov ntsia hlau; Qhov sib txawv ntawm lub ncoo deformation yuav ua rau cov tsheb ciav hlau tsis sib xws, ua rau lub zog nrawm nrawm thiab lub bolt loosening, ua rau txoj kev tsheb ciav hlau nkag mus thiab ntsuas qhov dav, ua rau muaj kev nyab xeeb kev nyab xeeb.
Q5: Yuav ua li cas tswj qhov nruj thiab deformation lub xeev nyob rau hauv -rail pads nyob rau hauv kev khiav hauj lwm thiab txij nkawm?
A5: Tsis tu ncua xyuas qhov deformation, hnav thiab txhim kho cov xwm txheej ntawm cov ntaub qhwv, thiab hloov cov ntaub qhwv nrog ntau dhau compression deformation; kho cov thickness thiab cov qauv ntawm cov ntaub qhwv raws li cov kev sib tw khov kho kom zoo dua qhov kev sib tw tag nrho; xyuas kom lub hauv paus nruab nrab ntawm cov ntaub qhwv kom tsis txhob deformation hauv zos aggravated los ntawm eccentric siab.
